DEVICE FOR PRINTING ON LEAD-PENCILS.

SPECIFICATION forming part of Letters Patent No. 630,149, dated August1, 1899.

Application filed Mayl7, 1899. Serial No. 717,134. (No model.)

To will whom, it may concern,.- y

Be it known that I, FRANK EWELLINGTON, of ITVOrCeSter, county ofVorcester, State of Massachusetts, have made certain new and usefulImprovements in Devices for Printing on Lead-Pencils, of which thefollowing is a description sufficiently full, clear, and exact to enableany person skilled in the art or science to which said inventionappertains to 1o make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in which-LFigure l is a top plan view of my improved pencil-printing device; Fig.2, an under side plan view of the stamp-bearing slide; Fig. 3, avertical section on line 3 3 in Fig. I, and Fig. 4 a sectional View online 4t 4c in Fig. 3.

Like letters of reference indicate corresponding parts in the differentfigures of the 2o drawings.

My invention relates especially to a mechanism forimprintinglead-pencils,button-hooks, and any cylindrical or rounded surfaces withnames, trade-marks, addresses, and other advertising matter. This isusually accomplished by indentations effected by a die and necessitatesthe use of expensive machinery and apparatus.

My invention has for its particular object 3o the providing of a cheapsimple eective device whereby anvink or stencil imprint may .be impartedon such articles without the employment of skilled labor.

The nature and operation of the improve- 3 5 ment will be readilyunderstood by those couversant with such matters from the followingexplanation.

In the drawings, A represents the body of the device, which comprises arectangular 4o base B, on which are arranged two vertical parallel sidepieces C, which form tracks or ways for a movable platen or type-bearingslide D. This slide D comprises a rectangular plate having at its endspendent guideflanges f, which overlap the ways C and di-4 For making theimprint I preferably einploy a rubber stamp g; but type or any otherprinting material may be substituted, it' de-v sired. This stamp ismounted on a spongerubber base h, which is cemented or otherwise securedto a metal plate t', secured by adjusting-screws j to the inner face ofthe slide D. Between the metal plate and said slide'strips ofspring-rubber 7c are disposed. As will be understood, the purpose ofthis rubber base and the strips is to permit the stamp to yield, andwhen adjusting by means of the screws to act expansively, that allportions of the lettering may bear against the pencil or other articleto be imprinted. Metallic springs may of course be substituted for therubber without departing from the spirit of my invention.

In the side pieces or tracks C two parallel shafts m m are journaled andbear a series of supporting-wheels p p. These wheels are mounted on theshafts with a tight sliding tit and are adjustable longitudinallythereof, as indicated by dotted lines p2 in Fig. l. The wheels 19 on therespective shafts are arranged, preferably, in alinement, as shown, andthe pencil t or other article to be imprinted rests loosely on saidwheels, where it may be readily rotated. It will be understood thatthese wheels may be varied in size to compensate for the variation indiameter of the article to be printed, raising or lowering it, as thecase may be, that the stamp g may be engaged properly therewith.

In one side plate or track C there is an opening 1J in alinement withthe pencil to admit extra lengths.

Shafts Iw are journaled in the tracks C, respectively, at opposite sidesof the supportingwheels, and these shafts carry cylindrical inking-rollsin position to be engaged by the face of the stamp or type g as theslide D is reciprocated on the tracks. Gne only of these inking-rollsmay be employed.

On the under face of the slide D there is a feederz. This feederhas aserrated face (see Fig. 52 in the same horizontal plane as the type andis rigid, or said feeder may consist of a block with a facing ot'sandpaper or emery, its purpose being, as the slide is advanced, toengage the pencil t and rotate it on the'bea1ing-wl1eelsp while thestamp is pass ing over it. This feeder I deem an essential feature, asby its use blurring of the imprint is prevented, such imperfection beingliable to occur when the pressure of the stamp itself is relied upon torotate the pencil, particuA larly when said stamp is of rubber; but inmany cases the feeder may, nevertheless, be dispensed with.

In use the pencil or other article being disposed on the bearing-rollsp, as shown in Fig. 1, the slide D is advanced. The stamp g is inked bythe adjacent roll as it passes over it. The feeder z engages the penciland begins to rotate it. Then the stamp g engages f the surface of saidpencil, and being on the vface at the same rate of speed.

same slide as the feeder passes over its sur- It Will be seen that bythis means the rubber stamp may give to. the pressure and conform to thecurved surface of the pencil Without slipping,

v and hence Without blurring the imprint.

It will be understood also .that a plurality -of stamps may be arrangedon the slide and the supportin grollers arranged to clear them, so thatas much of the surface of the pencil as desired may be printed.

Having thus described my invention, vvhat I claim is- 1. A device forimprinting the surface of cylindrical bodies comprising the roller-bedfor supporting said body; a slide fitted to be moved over said body andcarrying a typeand rollers arranged as specified; the removable slideWorking' on said tracks; and the stamp-spring cushioned on said slideand carried thereby.

4. The tracks and devices for supporting a rotatable cylindrical body incombination with a slide; a stamp carried by said slide in linetangential of said body and a springcushioned support for said slide.

5. In a device of the character described a roller-support for thepencil in combination with the slide; the stamp carried thereby andarranged tangentially of said rollers; and the feeder carried by saidslide substantially as and for the purpose speciiied.

6. In a device of the character described the slide in combination withthe horizontal stamp, g, the rubber cushion secured to said stamp and aspring-tensioned plate secured t'o said cushion and ad justably securedto said slide substantially as and for the purpose specified.

7. In a device of the character described a bed upon which a cylindricalbody may be rotated and supported in combination With a slide Working onsaid bed; a stamp on said slide for imprinting said body; and a feederon said slide adapted to engage said body and start it rotating beforesaid stamp engages it and maintain said rotation until said stampdisengages from said body. -l

8. In a device ofthe characterdescribed the bed and tracks; the shaftsbearing adjustable rollers; the shaft bearing the ink-roll; the slide;the spring-tensioned stamp on said slide; and the feeder on said slideall being combined and arranged to operate substan tially as specified.

In testimony whereof I have hereunto subscribed my name in presence oftWo Witnesses.
